Who did you use for the study?Yes, we are very happy with the outcome. That was four years ago now and I would do it again. We tore out an old Hydrospray IBA when we bought it and installed a used Laser 4000. About a week ago we tore out the Laser 4000 and will be installing a Razor in about a month. I will say that a feasibility study or a concept study is a GREAT idea. We did this and it was the absolute best money we spent on the entire project. Even if it was only confirming what we already thought was true.
